Holomorphic factorization of determinants of Laplacians using quasi-Fuchsian uniformization
英文摘要:
For a quasi-Fuchsian group $\Ga$ with ordinary set $Ω$, and $Δ_{n}$ the Laplacian on \n differentials on $\Ga\bkΩ$, we define a notion of a Bers dual basis $ϕ_{1},...c,ϕ_{2d}$ for $\kerΔ_{n}$. We prove that $\detΔ_{n}/\det <ϕ_{j},ϕ_{k}>$, is, up to an anomaly computed by Takhtajan and the second author in \cite{TT1}, the modulus squared of a holomorphic function F(n), where F(n) is a quasi-Fuchsian analogue of the Selberg zeta Z(n). This generalizes the D'Hoker-Phong formula $\detΔ_{n}=c_{g,n}Z(n)$, and is a quasi-Fuchsian counterpart of the result for Schottky groups proved by Takhtajan and the first author in \cite{MT}.
